Understanding /proc/interrupts

241 ratings | 33049 views
More videos like this online at http://www.theurbanpenguin.com Some devices such as the keyboard and parallel port are wired direct through to the CPU and use interrupts, or ask the CPU to stop and listen to them. We can view these interrupts in Linux from the file /proc/interrupts, so lets look and explain what is happening.

+Phil Campeau Could be that it shows interupts but doesn't actually explain what a interrupt actually is. Something do to with keyboards, devices. Not enough info for a complete novice to Linux admin like me.
